Planet Calypso is the first planet in the Entropia Universe and has been successfully running since 2003 with more than 950,000 registered accounts from 200 countries and territories with $428 million USD processed in player-to-player transactions in 2010.

"Virtual worlds are continuing to shine and grow within the gaming industry and our Guinness World Record complements our support for the future prosperity and progress of the space," said Martin Biallas, CEO of SEE Virtual Worlds. "The purchase of Planet Calypso is a testament of our commitment to the social online game world and is just one of the many steps we are taking in the thriving industry."

"We've seen enormous growth in the amounts for which digital property can be bought and sold over the last five years, and it's great to finally see the first multi-million dollar virtual item change hands," said Gaz Deaves, Editor of the Guinness World Records Gamer's Edition. "Guinness World Records is dedicated to chronicling all that is extraordinary and exceptional within the interactive gaming space and this acquisition certainly qualifies."

SEE Virtual Worlds is the publisher behind the highly anticipated Planet Michael, a first-of-its-kind interactive gaming and social experience that truly celebrates Michael Jackson's artistry and his messages of love and peace, and a Universal Monsters world featuring Van Helsing and Universal Studios' legendary line of cinematic monsters. The company also recently acquired the assets of First Planet Company, now rebranded as "SEE Digital Studios," which will continue to enhance Planet Calypso.

Guinness World Records 2011 Gamer's Edition is currently available in bookstores and in eBook format.  SEE Virtual Worlds' record will be featured in next year's edition.
